Refer to the exhibit. Which option is the result of this configuration?
A. Devices in OSPF area 15 can reach the summary route 192.168.0.0/16 and its more specific subnets.
B. Devices in OSPF area 15 can reach only the more specific routes of 192.168.0.0/16.
C. Devices in OSPF area 0 can reach the summary route 192.168.0.0/16 and its more specific subnets.
D. Devices in OSPF area 0 can reach only the summary route of 192.168.0.0/16.
Assuming the configuration is done at an ABR between area 0 and 15, it effectively isolates this subnet from the rest of the OSPF network.
That’s the only way “A” makes sense.

area 15 range XXXXXXXX not-advertise means that prefix XXXXXXXXX (including all subnets) that are in area 15 will not be advertised to other areas… so area 0 routers cannot reach XXXXXXXXXX.
area 0 routers cannot reach the prefix and all the subnets of it… ! No matching option
yes bart.. I totally agree with you..
I am not sure how come 1st choice being selected.. To my cognizance, none of the answers are correct echoing the same as your thoughts
I can’t see how A is correct.
not-advertise will make sure 192.168.0.0/16 is not advertised (summary, or specific) into area 15.
I don’t see any of the answers being correct.
